IMPROVEMENT IN EXTENSION BOW-1RONS FOR CARRIAGE-POLES- Specificationforming part of Letters Patent No. E93,2fi3, dated July 17, 1877application filed June 14, 1876.

To all whom it may concern:

Be it known that I, CHRISTIAN K. MELLIN- GER, of the city of Harrisburg,county of Dauphin, and State of Pennsylvania, have invented certainImprovements in Extension Bow-Irons for Carriage-Poles, of which thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, in which- Figure 1 represents oneend of the carriage-pole bow with my improved extensionirons theretoapplied. Figs. 2, 3, and 5 are detail views, representing, respectively,the socket-plate, the shackle, and the keeper; and Fig. 4 is across-section of the bow-irons, taken at P, Fig. 1

My present application is an improvement on my patent of October 1,1867, No. 69,356.

The shackle-plate, as formerly made and united with the bow or wood-workof the pole, was less elegant in appearance, as the finish was more orless defaced by the act of adjust ment; and as the bolts in theelongated slots in the shackle-plate admitted of a degree of lost motionor slackness of fit, the parts would be less firmly united than isdesirable; and the device also had less compass of adjustment than isrequisite. 1

My present application is therefore designed to obviate all theforegoing objections, and to produce a superior article by theconstruction and arrangements of certain new and useful parts,consisting of, first, a socket or bed plate permanently attached to theunder side of the 'bow, adapted to admit the wood into its socketed end,and to admit the shackle into a box securely -and firmly clamped thereinat its slotted end; second, a shackle slotted extensively in its body;third, a keeper-plate, suitably flanged to admit the shackle-bed, and toclose the bed-plate box in manner to secure a neat exterior finish, andthat need not be shifted in adjusting the shackle.

The bed-plate E D F (shown in Figs. 1, 2, and 4) is provided with thesocket or cap W, into which the end of the bow H is fitted by tenon, insuch manner as to dress flush exteriorly with the rounded form D of thesocket,

thus securing a firm and elegant joint. Said plate is also provided withholes 9 g g for the ordinary bolts m m n n, by which the keeper-plate O0 is applied, and is provided with holes a a) a for'wood-screws, bywhich the bed is permanently attached to the under side of the bow H.Said bed-plate, at its inner end, has a splice-joint, F, in which is thescrewhole 10, adapted to join the similar splicejoint F of the ordinaryT-plate. Said bedplate is made box form on its under side, havingstepped side flanges E, between which the shackle-bed K is admitted, andon which the keeper G G is applied, as shown in Fig. 4..

The recess at the bottom of the box is calculated to snugly admit thebed of the shackle, so that the bolts m n may pass loosely through theslot L of the shackle, and yet secure the shackle firmly to its place ofduty simply by close confinement in the box by the keeper 0 G Theshackle (shown in Fig. 3) is made with knuckle A, bent arm B, and bed K,extensively slotted at L to allow it to be extensively adjusted, and yethave both bolts m and'n in the slot L. Moreover the front bolt and nut MM may be inserted at O, and the shackle and keeper-plate Usetaccordingly, when the reach or spread of shackle-clips requires thebow to be shortened or retracted extensively-as, for example, onsleighs.

The keeper-plate O U is made lid form-the complement of the boxon thebed-plate, as shown in Fig. 4. It has on it the flanges (3 and betweenthem the groove N, in the floor of which is the slot L, correspondingwith slot L of the bed:platc l) E.

The flanges and grooves of the keeper-plate and those of the bed-plateare constructed, relatively to each other, so as to form, when united, areceptacle for the body K of the shackle of such exact depth that whenthe keeper 0 O is forced down by the nuts mm, to close the box theshackle will be clamped to place by the keeper, and it may be adjustedby a partial release of said nuts, after which it may again be clampedwithout removing the keeper-plate, thus preserving the paint or othersurface of finish on the exterior of the device.

The operations have been explained en passant, and its merits are soobvious that no description can make more manifest its utility.

Having therefore fully and clearly set forth my invention, what I regardas new and useful I here embrace in the following claims:

1. The bed-plate E F, when provided with the socket D W, for theinsertion therein of the end of bow H, substantially as and for the vpurpose set forth.

2. The bed-plate E F, provided with the splice-joint F, in combinationF, and the how H, substantially as set forth.

3. The bed-plate E F and the keeper-plate 0 0 when provided with flangesE and "0 with the T-platerespectively, and combined by bolts m n andnuts min, substantially as set forth, as a shackle-casing.

4. The bed-plate E F, shackle A B K, and

keeper-plate O 0 all constructed and applied CHRISTIAN K. MELLINGER.
